The hardness of the material is correlated to the wear resistance of the material. If the hardness of the material is less than that of the hardness of the abrasive material, then the wear rate is high. The hardness of material plays a major role in wear resistance. Some materials exhibit special wear characteristics. Wear-resistant Materials
